Flotation kinetics of coal in the Inflatable Cyclonic Flotation Column
Powder Technology, 2018 This paper mainly investigates the flotation kinetics of coal in the flotation column. The flotation tests were carried out in the Inflatable Cyclonic Flotation Column (ICFC) which consists of two parts, i.e., the inflatable flotation unit and the cyclone flotation zone.

Selectivity in phosphate column flotation
Minerals Engineering, 2007Abstract The objective of this work was the study of the selectivity of apatite flotation in a column by means of kinetic analysis. The recovery and apatite content in the concentrate were correlated to the collector dosage, depressant dosage and air flow rate.

Beneficiation of fluorspar by column flotation
Mining, Metallurgy & Exploration, 2000 The amenability of column flotation for the beneficiation of fluorspar was investigated, and the overall performance of the column flotation was compared to the performance of the existing conventional flotation cells at the plant. It was established that improved grades and recoveries could be obtained by adopting column technology.

Flotation behaviour of weathered coal in mechanical and column flotation cell
Powder Technology, 2013 The low rank or oxidized coals show unpleasant flotation behaviour. The non-coking coal from Talcher, containing 26.8% ash, 4.9% moisture, 35.7% volatile matter and 1% oxygen was used for the investigation. The flotation performance of the weathered coal

Application of Flotation Column on Flotation of Copper Ore
Advanced Materials Research, 2013Two flotation columns replacing traditional flotation machine and vertical agitate mill were successfully used on copper production in Yangla mine. With introducing of these advanced machines, chalcopyrite with fine dissemination size could be absolutely liberated. In addition, the technological process was further optimized.
